Many thanks Mark, Great build. Regards, A.R

Hi, I used to be metric guy like you too. In uni never came to terms with imperial units. Once I started this hobby things changed, I can move between imperial,metric and fractional without even thinking about it. I bought a cheap fractional vernier and converted all the plans dimensions to...

Hi, Have you got a build log for the engine? Regards, A.G

Hi, It is a bore micrometer, do you have all the rods? A.G

Hi, Jan was kind enough to let me know that he has used the Fortuna Optima glass syringe, I have not been able to find a supplier for these in the UK even though the parent company is listed on the web. The test tubes that I have got on the eBay have not been suitable so far. So if accuracy...

Hi Titex, Many thanks for your reply, That is probably why hardly anyone uses them in the hobby sector of the UK. BTW they are not alone in charging such prices, a while back I bought a Sumitomo carbide boring bar, 6 mm dia, for about £38.00 including a tip, the tip was a weird looking affair...

Well done Kadet, You have just proven what could be achieved with a little bit of ingenuity and drive, a running engine from common as muck materials. Congratulations. Regards, A.G

Hi mwilkes, It looks beautiful, well done. I was thinking of doing a 10 V as my first engine from casting to run on real steam until I found out the prices that are being asked for boilers. I am quite envious now. Regards, A.G

Hi Tin F, My work horse is my little Taig lathe fitted with a Sherline Dc motor and controller. When I use carbide, mostly indexed tips from Sandvik and Iscar, I have learned not to be frightened of turning the speed control up all the way and engage the auto feed at max speed with my right...

Hi, I have at least 8 air-steam engines of bar stock construction under my belt and I was considering a Stuart engine from castings for my next project as I wanted to use sream rather than air to power it. Despite having reservations about my ability to machine the castings the real deal...

Hi Gerry, Many thanks, it is almost entirely made of Aluminium and a little Brass. All the inside of the engine is made of either 7075, 2011, 2014 Aluminium or EN1a Pb steel, the cylinders and the crankcase are 6082 and the flywheel and the bits on the top are brass. Tonight I ran the engine...

Hi Gus, Hope you don't mind me saying that the right temp for the silver steel is when the colour is like cooked carrots not dark chili or cherry or etc, it just won't be hot enough. I do mine in my garage and just partially block the light, don't want to suffocate. You only really need to...

Hi, The reason that I was interested in the HSS inserts is that they are supposedly, have a hardness factor of over 64 HRC but do not chip or crack like carbide, even a hardened and tempered piece of silver steel is about 54 HRC and drill bits are even lower. I have now bought a Myford ML7 and...

Hi , What kind of milling machine do you have? Regards, A.G

Hi, Just as a matter of interest, has anyone seen HSS inserts in the UK? These seem to have a strong following in the US as they combine the best qualities of the carbide inserts without their weakness, chipping, gigh speed and high feed rate requirement and so on? A.G

Hi, Great looking engine, well done. A.G

Hi, The most important parts of this engine are 1- the wobble plate 2- the valve, this needs to be free to move but as air tight as possible to prevent the air pressure loss. Better off machining the diameter quite tight to the bore and then loosen it by lapping froward and back. Good...

Thanks Dave, Will do as advised, 3 radial 5s and a 10 cylinder, way out of my league I'd say but now I know whom to go to for advice. Best wishes, A.G

Thanks Jim, Yes I do still have a mantelpiece, it will probably end up there with the other six or seven engines that I have built. Many happy returns to you too. Regards, A.G

Hi everybody, Just wanted to say thanks to all those who advised me during the build of this engine, I have attached a photo of the finished engine and yes it ran the first time once I hooked everything up. I just need a proper air compressor to keep it going as mine is for very small air...
